INA128UA/2K5

INA128UA/2K5 is the 2,500-piece tape-and-reel SOIC-8 ordering code for the Texas Instruments INA128 instrumentation amplifier, listed as Active Production in the current datasheet (SBOS051G) package option addendum. Every figure here is the UA grade read on its own rows: input offset voltage of ±25 µV typical and ±125 µV maximum, offset drift of ±0.2 µV/°C typical and ±1 µV/°C maximum, common-mode rejection of 73 dB minimum at unity gain on the conservative wafer-source column (the current datasheet splits several rows by wafer fab, and this page quotes the lower figures), a 1.3 MHz bandwidth at unity gain, supply current of ±700 µA typical and ±750 µA maximum, and operation from ±2.25 V to ±18 V with gain set as 1 + 50 kΩ/RG from 1 to 10,000. The selection point is the classic three-op-amp instrumentation front end for bridge and sensor signals at a grade priced for volume designs. Selection advice: the headline offset and CMR figures on the TI product page belong to the P and U grades, not to this UA code - design the error budget from the UA rows above, and confirm which wafer-source column your accuracy target needs before locking the BOM. Parameters verified against the TI INA128 datasheet SBOS051G (package option addendum and the UA-grade electrical table).
